Hi. I can't sync Firefox from my old Surface Pro 2 to my new Surface Pro 3. Both run windows 8.1. Firefox synced OK over a year ago to my Surface 2 OK but I lost the password.

On SP2, I updated FF, deleted the old Sync account and set up a new Sync account. On SP3, I set up the same account. When I sign in to the SP3 sync account, the message "Sync will start momentarily" displays but nothing happens.

Following your forum suggestions, I made these changes to both SP2 and SP3. 1. Disconnect and reconnect to Sync. 2. Delete the signedInUser.json file in the profile folder with Firefox closed and possibly delete the Weave folder as well. 3. Delete and re-create the FxA account. at https://accounts.firefox.com/settings

I also Reinstalled FF on SP3. Same message but won't sync. Appreciate any suggestions.

Progeny again: Problem solved! While waiting for a reply I logged in again to Sync on both SP2 and SP3. Same message "Sync momentarily" but no sync. Then I noticed menu bar was missing on SP3 FF. While fixing that I found your Q and A on how to fix corrupt toolbar - Go to Menu/Customize and click on "Restore Defaults". That walked me back through the FF start up. I chose FF as my default again BUT this time on the next step I choose to use Firefox NOT Internet Explorer. (on my 1st FF setup I choose IE because the FF choice produced a message saying IE could not complete the install). That done, the SP3 Sync immediately synced with the SP2!! Trust this fix helps anyone with the same issue.
